RECORDING MECHANISM.

Specification of Letters Patent. Patented D 21 1920 Application filed October 29, 1919. Serial No. 334,177.

To wll'whom itmay concern: p

Be it known that I, SAMUEL J. MAsoN, a citizen of the United States, and a resident of Perth Amboy, in the county of Middlesex and State of New Jersey, have invented a new and Improved Recording Mechanism,

of which the following is a full, clear, and

exact description.

This invention relates to improvements in recording mechanisms, andmore particu larly toa device for recording the velocity of water, an object of the invention being to provide a marking device engaging a movable record and operated by means of magnets which are caused to move by the variation in velocity of waterin a main or other conveyer.

A further object is to provide improved means for mounting magnets within a casing operated by a float controlled by variations in pressure due to variations in velocity, said magnets operating to move an armature which controls the movement of a marking device, the latter adapted to record such movement upon a record sheet or disk.

With these and other objects in view the invention consists in certain novel features 'of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 1s a view in longitudinal section illustrating my improvements;

Fig. 2 is an enlarged view in transverse section on the line 2-2 of Fig. 1; and

Fig. 3 is a View in transverse section on the line 3-3 of Fig. 1. 1 re resents a casing and 2 a water main, the velbcity of the water in which latter is to be recorded. The casing 1 is divided by a horizontal partition 3 into upper and lower chambers land 5 respectively. In the center of the lower chamber 5 a cylindrical barrel 6 is located and communicates at its upper end with the chamber 4 and at its lower end has a communicating opening 7 connecting the lower end of the barrel 6 with chamber 5.

A tube 8 of' relatively thin metal is se cured in the top 9 of casing '1 and is made of the barrel, although these details may, of course, be varied without departing from the invention.

A pipe 12 connects the upper portion of chamber 5 with the main tube and a pipe 16 connects the upper portion of chamber 4 with the main tube. These pipes 12 and 13 are flared apart at their free ends, as shown at 14, and are positioned in the main and in accordance with the flow of water as indicated by the arrows. In the lower portion of chamber 5 and barrel 6 the desired quantity of carbon-tetrachlorid 15 or other liquid of greater specific gravity than water is provided, while the other space in the casing is filled with water as indicated.

A float 16 is provided in barrel 6 and is provided with a plurality of upwardly projecting rods 17 which extend into the chamber 41 and are connected to a ring 18. This ring 18 supports a series of horseshoe magnets 19 and a series of floats 20. The ends of the magnets 19 are preferably beveled, as shown at 21, and are located in proximity to the wall of the pipe 8.

A circular armature 22 is located in the pipe 8 and is attracted by the magnets 19. This armature 22 is preferably made with beveled edges corresponding'to the beveled ends of the magnets and is connected to a central float 23 and provided with rollers 24: to engage the inner wall of pipe 8 and reduce friction to a minimum. A pen carry- In operation the attraction of the magnets 19 maintains the armature 22 in alinement therewith and the magnets are moved vertically by the float 16. The movement of the float 16 is caused by the variation in pressure within chamber 5 which depresses the carbon-tetrachlorid in said chamber and with an open upper end 10 and a lower forces the carbon-tetrachlorid longitudinally closed end 11. The tube 8 is located centrally relative to the barrel 6, but is of appreciably less diameter than the barrel and terminates at 'a point, above the upper end of the barrel 6.

The proportion of movement can be varied by variation in the surface areas of the chamber 5 and the barrel 6 and the movethe float 23 can operate to counterbalance the weight of the armature and the other parts connected thereto, and hence render the device extremely sensitive to the movement or the magnets.

While I have illustrated what I believe to be a preferred form of my invention, it is' obvious that the general ideas illustrated may be incorporated in other forms of device, and hence I do not wish to be limited to the precise details oi construction set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:
